graphs of trig fx

study stack day 2

unit circle a unit circle is a circle with a radius of one.
reference angle The reference angle is the smallest angle between the terminal side and the x-axis.
trig values It is these ratios that the trigonometric functions express. To define the trigonometric functions for the angle A, start with any right triangle that contains the angle A.
special acute angles Angles smaller than a right angle (less than 90°) are called acute angles ("acute" meaning "sharp").
trig tables In mathematics, tables of trigonometric functions are useful in a number of areas.
trig functions functions of an angle
domain All the values that go into a function The output values are called the range
range The difference between the lowest and highest values.
amplitude , period , wavelength of trig waves frequency is the number of waves per unit time. Period is the reciprocal of that - the duration of a single wave. Amplitude is the magnitude of the wave - how high it goes on the y axis. Wavelength is basically the same thing as period -
